my check engine light just came on last night. what can i check? will it let me set? gas cap was on, and checcked the oil. lately i have been noticing a little bit of a rough engine deceleration or idling when you come to a redlight or stop sign. give me some suggestions. 2.9 litre with 60,000 miles. thanks

 

What model is it?

 

960 when i just started it up tonight it ran rough. although driving along seems ok. thanks

 

It could be many things if it is a 1995 or older 960 you can pull codes your self.
